Bug Description

get_snat_port_for_internal_port retrieves the internal snat port created for each router interface added to a DVR router.
But this function is called twice in the L3 agent code.

for every interface add or delete to the router, it is called by the '' and again it is called by the ''.

This can be reduced to a single call to improve the controll plane performance.
